This work involves a process of audification of the seismological data record, which occurred in the area of New York State, New Jersey, and New England during the collapse of the World Trade Center buildings on September eleventh, 2001. The data streams were acquired from Columbia University's Geological survey lab, which run a network of earth monitoring stations in the area; with the closest being 34 km away from the epicenter of the event. A process of data conversion and signal translation was used to make the normally inaudible seismic waveforms both audible and to play back in real-time as the event unfolded. No other processing or effects were added to the tracks. The registration includes four events, two impacts and the two collapses along with the inbetween sounds of the drone of the earth. The heaviest impact of the collapse registered 2.4 on the Richter scale, a signal which traveled throughout the earth. This work stands not as a memorial per se but as an action of affect, where the global terrain becomes a sounding board, a bell-like alarm denoting histories in the making.
